Paper Abstract

The spatio-temporal dynamics of the broad-area photonic crystal surface-emitting laser is investigated numerically. Excitation of the high-order transverse modes can result in transition from one type of a transverse field distribution to another. Such process is similar to spontaneous symmetry breaking and mode competition in broad-area lasers. Formation of a complex transverse field distribution in photonic crystal surface-emitting laser depends on transverse distribution of pump and on initial conditions. Photonic crystal surface-emitting laser generates the fundamental mode independently on initial conditions only for a small area of a pump region. The modification of the pump region allows to control the transverse structure of an output laser beam.
